Just after midnight on Thursday the UAW announced on its Facebook page that “after a lengthy bargaining process, your UAW FCA National Bargaining Committee has secured significant gains in a proposed tentative agreement with FCA announced today.”

Neither side disclosed the agreements’ details. It will discussed in Detroit on Friday morning by the UAW National Chrysler Council, and its members will vote on whether to give it the initial go-ahead to face a ratification vote by the union’s rank-and-file.

FCA was under tremendous pressure on to reach a deal since the UAW on Tuesday said that if there was no new contract as of 11:59 p.m. on Wednesday, its existing agreement would no longer be in effect and it might call for a worker strike.

The current pact between UAW and FCA expired on September but it was extended during ongoing talks between the two sides. They reached a tentative deal on September 15, but the union members dismissed it handedly with a 65% no vote—the first time UAW members had dismissed a national agreement in 33 years. That rejection brought the UAW bargaining members and FCA leadership back to the negotiating table.

The deal would have shrunk the pay gap between long-term workers and their entry-level counterparts, but it did not achieve what they’re really after: a full path for entry-level workers to transition to the higher tier—where average pay is $28 per hour—and a cap on the share of FCA workers who are relegated to the entry-level.

UAW workers will have to wait until Friday to see if the new deal brokered Thursday gives them what they want.
